Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of sweet sorghum harvesting, pressing, and storage devices, and more specifically, the present invention relates to an integrated sweet sorghum harvesting, pressing, and storage machine. Background Technology

[0002] Sweet sorghum typically has a sugar content of 15%-22% and exhibits strong resistance to drought, flooding, salinity, poor soil conditions, and high temperatures. Its stalks can reach a height of 4-6 meters, and its biomass yield is high, reaching 2-3 times that of corn. It can be planted on arid, saline-alkali, and barren marginal lands and is considered one of the most promising food and energy crops. Even after experiencing extreme weather events such as floods, droughts, and sandstorms, the yield of its core product remains fully guaranteed. This unique variety of sweet sorghum possesses advantages in saline-alkali land improvement and soil remediation, and can effectively form a comprehensive industrial chain development path.

[0003] Currently, the harvesting of sweet sorghum mainly relies on traditional agricultural machinery. Most of these machines can only perform a single harvesting function. After harvesting, the sweet sorghum stalks often need to undergo multiple transfers, loading and unloading, and long periods of stacking before they can be processed into juice, storage, and other subsequent stages. This process is not only inefficient but also increases labor costs and material losses.

[0004] In the processing of sweet sorghum juice, existing technologies typically involve directly collecting and storing the extracted juice, lacking further preservation or refining processes. This not only limits the application range of sweet sorghum juice but also risks spoilage due to prolonged storage, directly impacting the quality of the final product. Summary of the Invention

[0005] In order to solve one or more of the technical problems mentioned above, the present invention provides a sweet sorghum harvesting, pressing, frying and storage integrated machine, which can improve the juicing efficiency of sweet sorghum and prevent the sorghum juice from deteriorating.

[0006] This invention provides a sweet sorghum harvesting, pressing, and storage integrated machine, comprising:

[0007] Motor vehicles;

[0008] A harvesting device, which is mounted on the motor vehicle and used for harvesting sweet sorghum;

[0009] Juicing device, which is mounted on the motor vehicle, is used to press the harvested sweet sorghum to obtain sweet sorghum juice;

[0010] A storage device, mounted on the motor vehicle, is used for collecting and storing the extracted sweet sorghum juice; and

[0011] A heating component is disposed within the storage device and is used to heat, sterilize, and keep the juice warm.

[0012] Furthermore, the storage device includes a juice receiving hopper located below the juicing device for collecting the extracted sweet sorghum juice, and a storage tank connected to the juice receiving hopper for receiving and storing the sweet sorghum juice, wherein the heating assembly includes an electric heating wire located in the storage tank and powered by the power supply device of the motor vehicle, and / or a heating tube located in the storage tank and heated by the steam generator of the motor vehicle.

[0013] Furthermore, the juicing device includes:

[0014] The primary pressing unit is used to press the harvested sweet sorghum once;

[0015] A secondary pressing unit is used for a second pressing of the sweet sorghum after the primary pressing; and

[0016] A diffusion conveying device is provided between the primary pressing mechanism and the secondary pressing mechanism, and is used to diffuse the sweet sorghum after primary pressing into the secondary pressing mechanism.

[0017] Furthermore, both the primary pressing mechanism and the secondary pressing mechanism include a first frame, a first hollow pressure roller rotatably and slidably disposed in the first frame, a second hollow pressure roller rotatably disposed in the first frame, and an elastic pressure application component disposed on the first frame and connected to the first hollow pressure roller. When the first hollow pressure roller and the second hollow pressure roller rotate in opposite directions, they can transport the sweet sorghum that enters between the first hollow pressure roller and the second hollow pressure roller in a predetermined direction and press it by mutual squeezing. The elastic pressure application component controls the distance between the first hollow pressure roller and the second hollow pressure roller through its own elastic force to adjust the pressing force of the first hollow pressure roller and the second hollow pressure roller on the sweet sorghum.

[0018] Furthermore, the first frame includes a base, a first support arm and a second support arm that are both fixed on the base and parallel to each other, a first bearing seat and a second bearing seat that are sequentially fixed on the first support arm and the second support arm and respectively connected to the two ends of the second hollow pressure roller, and a third bearing seat and a fourth bearing seat that are sequentially slidably disposed on the first support arm and the second support arm and respectively connected to the two ends of the first hollow pressure roller, wherein the third bearing seat is located above the first bearing seat and the fourth bearing seat is located above the second bearing seat;

[0019] The elastic pressure application assembly includes a first hydraulic cylinder and a second hydraulic cylinder, and one or two pressure accumulators that are simultaneously or sequentially connected to the rodless chambers of the first hydraulic cylinder and the second hydraulic cylinder. The cylinder body of the first hydraulic cylinder is fixed on the first support arm, while its rod body is fixed on the first bearing seat. The cylinder body of the second hydraulic cylinder is fixed on the second support arm, while its rod body is fixed on the second bearing seat. The central axis of the first hydraulic cylinder and the central axis of the second hydraulic cylinder are arranged to pass through the central axis of the first hollow pressure roller and the second hollow pressure roller.

[0020] Furthermore, the integrated sweet sorghum harvesting, pressing, and storage machine also includes a gathering and conveying device and a crushing and throwing device installed on the motor vehicle. The gathering and conveying device is located between the juicing device and the crushing and throwing device, and is used to convey the pressed sweet sorghum into the crushing and throwing device, so that the crushing and throwing device can crush and throw the sweet sorghum.

[0021] Furthermore, both the diffusion conveying device and the convergence conveying device include:

[0022] Second frame;

[0023] The first conveyor is located within the second frame;

[0024] A fabric roller assembly includes at least two fabric rollers arranged at intervals above the first conveyor and along the length of the first conveyor. Each fabric roller includes a roller body rotatably disposed within a second frame, and a first helical blade and a second helical blade wound around the outer circumferential surface of the roller body. The first helical blade and the second helical blade are mirror-symmetric about a selected section of the roller body. The selected section is a section perpendicular to the central axis of the roller body and passing through the midpoint of the width direction of the roller body.

[0025] The fabric roller assembly and the first conveyor are clamped together to transport sweet sorghum along the length of the first conveyor. Each fabric roller in the fabric roller assembly causes the transported sweet sorghum to spread or gather in the width direction of the first conveyor through its respective first spiral blade and second spiral blade.

[0026] Furthermore, the conveying device also includes a transmission mechanism disposed in the second frame and connected to the plurality of fabric rollers. The transmission mechanism is used to transmit the power generated by the power unit of the motor vehicle to each of the fabric rollers, and to make the linear velocity of each of the fabric rollers decrease or increase along the conveying direction of the first conveyor.

[0027] Furthermore, the crushing and throwing device includes:

[0028] A conveying pipe, which is installed on the motor vehicle, is used to receive the pressed sweet sorghum;

[0029] A crusher, disposed within the conveying pipe, crushes the sweet sorghum passing through it; and

[0030] An exhaust fan is installed on the conveying pipe and is capable of discharging the crushed sweet sorghum outside the conveying pipe.

[0031] Furthermore, the integrated sweet sorghum harvesting, pressing, and storage machine also includes a feeding device mounted on the motor vehicle and located between the harvesting device and the juicing device. The feeding device includes a second conveyor and a feeding roller assembly mounted above the second conveyor. The feeding roller assembly and the second conveyor clamp the sweet sorghum along the length of the second conveyor.

[0032] The sweet sorghum harvesting, pressing, shoveling, and storage integrated machine provided in this embodiment integrates at least a harvesting device, a juicing device, and a storage device onto the same motor vehicle. It can even further integrate a crushing and shoveling device onto the same motor vehicle, giving this sweet sorghum harvesting, pressing, shoveling, and storage integrated machine superior performance by combining four major functions: harvesting, juicing, storage, and shoveling. This configuration not only achieves direct pressing and efficient collection and storage of juice from sweet sorghum, but also significantly improves the overall efficiency of sweet sorghum juicing by having the harvesting and juicing devices operate synchronously with the vehicle's movement. Particularly noteworthy is that the heating component within this sweet sorghum harvesting, pressing, shoveling, and storage integrated machine can heat and sterilize the sweet sorghum juice in the storage device and maintain its suitable temperature, effectively solving the problem of juice deterioration that may occur due to long operating cycles. This ensures the final quality and safety of the sweet sorghum juice, achieving optimization from field to storage. Attached Figure Description

[0053] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0054] Figure 1 This diagram illustrates the structure of a sweet sorghum harvesting, pressing, and storage integrated machine according to an embodiment of the present invention. Figure 2 This figure shows a side view of a sweet sorghum harvesting, crushing, and storage integrated machine provided in this embodiment. Figure 3 A cross-sectional view of the heating assembly 5 and the storage tank provided in this embodiment is shown. Figure 1 and Figure 3 As shown, this embodiment provides a sweet sorghum harvesting, pressing, and storage integrated machine, including a motor vehicle 1, a harvesting device 2, a juicing device 3, a storage device 4, a heating component 5, and a crushing and throwing device 7. The harvesting device 2 is mounted on the motor vehicle 1 and is used to harvest sweet sorghum; this is conventional technology in the field and will not be described in detail here. The juicing device 3 is mounted on the motor vehicle 1 and is used to press the harvested sweet sorghum to obtain sweet sorghum juice. The storage device 4 is mounted on the motor vehicle 1 and is used to collect and store the extracted sweet sorghum juice. The heating component 5 is located inside the storage device 4 and is used to heat, sterilize, and keep the juice warm. The crushing and throwing device 7 can crush and throw the pressed sweet sorghum.

[0055] The sweet sorghum harvesting, pressing, shoveling, and storage integrated machine provided in this embodiment integrates at least a harvesting device 2, a juicing device 3, and a storage device 4 onto the same motor vehicle 1. It can even further integrate a crushing and shoveling device 7 onto the same motor vehicle 1, giving this integrated machine superior performance by combining harvesting, juicing, storage, and shoveling into one system. This configuration not only achieves direct pressing and efficient collection and storage of juice from sweet sorghum, but also significantly improves the overall efficiency of sweet sorghum juicing by having the harvesting and juicing devices 3 operate synchronously with the vehicle's movement. Particularly noteworthy is the heating component 5 within this integrated machine, which can heat and sterilize the sweet sorghum juice in the storage device 4 and maintain its suitable temperature. This effectively solves the problem of juice deterioration that may occur due to long operating cycles, thus ensuring the final quality and safety of the sweet sorghum juice and achieving optimization from field to storage.

[0056] Furthermore, the storage device 4 includes a juice receiving hopper 41 located below the juicing device 3 for collecting the extracted sweet sorghum juice, and a storage tank 42 connected to the juice receiving hopper 41 for receiving and storing the sweet sorghum juice. The heating component 5 includes an electric heating wire (not shown) located within the storage tank 42 and powered by the power supply of the vehicle 1, or a heating pipe 51 located within the storage tank 42 and heated by the steam generator of the vehicle 1. The storage device 4 utilizes the juice receiving hopper 41 located below the juicing device 3 and the storage tank 42 connected thereto. This arrangement aims to efficiently capture and collect the freshly extracted sweet sorghum juice from the juicing device 3. The juice receiving hopper 41, as a key component connecting the juicing and storage stages, precisely guides the juice into the storage tank 42, ensuring smooth collection and proper preservation of the juice. The heating component 5 is carefully configured inside the storage tank 42, including two options: one is an electric heating wire (not shown) powered by the vehicle's own power supply system, and the other is a heating tube 51 that uses the vehicle's steam generator to provide heat. The electric heating wire or heating tube 51 not only heats the sweet sorghum juice in the storage tank 42 in real time, effectively performing sterilization, but also maintains the juice within a suitable temperature range, resolutely preventing spoilage caused by long operating cycles. This ensures that the sweet sorghum juice does not deteriorate due to prolonged operation time during the sweet sorghum harvesting, pressing, and storage integrated machine. The electric heating wire is directly connected to the vehicle's power supply, while the heating tube 51 seamlessly connects to the vehicle's steam generator, fully utilizing the vehicle's own energy supply without requiring additional energy equipment. This greatly simplifies the overall structure and improves the system's integration and operating efficiency.

[0057] Furthermore, the juicing device 3 can have one or more pressing stages. As an example, such as... Figure 2As shown, the juicing device 3 includes a primary pressing mechanism 31, a secondary pressing mechanism 32, and a diffusion conveying device 33. The primary pressing mechanism 31 is used to perform a first pressing on the harvested sweet sorghum. The secondary pressing mechanism 32 is used to perform a second pressing on the sweet sorghum after the first pressing. The diffusion conveying device 33 is located between the primary pressing mechanism 31 and the secondary pressing mechanism 32, and is used to diffuse the sweet sorghum after the first pressing into the secondary pressing mechanism 32. The primary pressing mechanism 31 performs the first pressing on the sweet sorghum, mainly pressing the whole sweet sorghum stalks. The sweet sorghum after being pressed by the primary pressing mechanism 31 is then conveyed to the secondary pressing mechanism 32 via the diffusion conveying device 33, where it further presses the sweet sorghum after being pressed by the primary pressing mechanism 31. The two pressing processes—one by the primary pressing mechanism 31 and the other by the secondary pressing mechanism 32—maximize the extraction of sorghum juice, thus increasing the juice yield. Furthermore, the diffusion conveying device 33 not only transports the sorghum from the primary pressing mechanism 31 to the secondary pressing mechanism 32, but also forces it to diffuse along its width during transport. This allows the sorghum discharged from the outlet of the primary pressing mechanism 31 to gradually adapt to the inlet of the secondary pressing mechanism 32, ensuring that the secondary pressing mechanism 32 receives more of the sorghum after the primary pressing and performs more thorough pressing.

[0058] Figure 4 A schematic diagram of the primary pressing mechanism 31 provided in this embodiment is shown. Figure 4 and combined Figure 1 and Figure 2As shown, both the primary pressing mechanism 31 and the secondary pressing mechanism 32 include a first frame 311, a first hollow pressing roller 312 rotatably and slidably disposed in the first frame 311, a second hollow pressing roller 313 rotatably disposed in the first frame 311, and an elastic pressure application component 314 disposed on the first frame 311 and connected to the first hollow pressing roller 312. When the first hollow pressing roller 312 and the second hollow pressing roller 313 rotate in opposite directions, they can transport the sweet sorghum entering between the first hollow pressing roller 312 and the second hollow pressing roller 313 in a predetermined direction (i.e., the length direction of the diffusion conveying device 33 or its conveying direction), and perform pressing by mutual squeezing. The elastic pressure application component 314 controls the distance between the first hollow pressing roller 312 and the second hollow pressing roller 313 through its own elastic force, so as to adjust the pressing force of the first hollow pressing roller 312 and the second hollow pressing roller 313 on the sweet sorghum. The effective directional conveying of sweet sorghum is achieved through the counter-rotation mechanism of the first hollow pressure roller 312 and the second hollow pressure roller 313. During this process, the first hollow pressure roller 312 and the second hollow pressure roller 313 work together to apply pressure to the sweet sorghum, thereby efficiently extracting its juice. Furthermore, the elastic pressure application component 314 can adjust the distance between the first hollow pressure roller 312 and the second hollow pressure roller 313 to adapt to the pressing needs at different stages. Specifically, when the sweet sorghum initially contacts and attempts to enter between the first hollow pressure roller 312 and the second hollow pressure roller 313, the elastic pressure application component 314 temporarily refrains from applying elastic force to the first hollow pressure roller 312, allowing it to be easily lifted by the sweet sorghum. This provides ample space for the sweet sorghum to enter smoothly, greatly reducing the difficulty of the sweet sorghum entering the pressing area and ensuring a smooth pressing process. Once the sweet sorghum is fully between the first hollow roller 312 and the second hollow roller 313, the elastic pressure application component 314 immediately comes into play. By applying a moderate elastic force, it pushes the first hollow roller 312 closer to and squeezes the second hollow roller 313, thereby achieving precise pressing of the sweet sorghum. This dynamic adjustment of pressing force not only improves pressing efficiency but also ensures a uniform distribution of pressing force, avoiding juice loss or damage to the sweet sorghum caused by uneven pressing. Furthermore, the hollow design of the first hollow pressure roller 312 and the second hollow pressure roller 313 significantly reduces the weight of the rollers, making the entire primary pressing mechanism 31 and the secondary pressing mechanism 32 lighter and easier to integrate into the sweet sorghum harvesting, pressing, and storage machine. The elastic force of the elastic pressure application component 314 adjusts the pressing force of the first hollow pressure roller 312 and the second hollow pressure roller 313, allowing them to efficiently press sweet sorghum while maintaining a lighter weight. This perfect combination of lightweight design and high-efficiency pressing allows the primary pressing mechanism 31 and the secondary pressing mechanism 32 to maintain high juice yield and processing efficiency while greatly reducing the difficulty of moving and deploying the sweet sorghum harvesting, pressing, and storage machine.

[0059] Furthermore, the first frame 311 includes a base 3111, a first support arm 3112 and a second support arm 3113 both fixedly mounted on the base 3111 and parallel to each other, a first bearing seat 3114 and a second bearing seat that are sequentially fixed on the first support arm 3112 and the second support arm 3113 and respectively connected to the two ends of the second hollow pressure roller 313, and a third bearing seat 3115 and a fourth bearing seat that are sequentially slidably mounted on the first support arm 3112 and the second support arm 3113 and respectively connected to the two ends of the first hollow pressure roller 312. The third bearing seat 3115 is located above the first bearing seat 3114, and the fourth bearing seat is located above the second bearing seat. By fixing the first bearing seat 3114 and the second bearing seat sequentially onto the first support arm 3112 and the second support arm 3113, and connecting the rotating shafts at both ends of the second hollow pressure roller 313 respectively, the second hollow pressure roller 313 can rotate while being confined by the first support arm 3112 and the second support arm 3113. Furthermore, by slidably arranging the third bearing seat 3115 and the fourth bearing seat sequentially onto the first support arm 3112 and the second support arm 3113, the first hollow pressure roller 312 can move closer to or further away from the second hollow pressure roller 313, allowing the elastic pressure application component 314 to adjust the distance between the first hollow pressure roller 312 and the second hollow pressure roller 313.

[0060] It should be noted that in this embodiment, the primary pressing mechanism 31 and the secondary pressing mechanism 32 have almost the same mechanical structure. The main difference is that their sizes are different. To save space, this embodiment only shows the structural schematic diagram of the primary pressing mechanism 31 and describes the specific structure of the primary pressing mechanism in detail.

[0061] The elastic pressure application assembly 314 can be any elastic device for applying pressure, such as an elastic device with a spring or gas spring as its core. As a preferred example, the elastic pressure application assembly 314 includes a first hydraulic cylinder 3141 and a second hydraulic cylinder 3142, and one or two pressure accumulators 3143 that are simultaneously or sequentially connected to the rodless chambers of the first hydraulic cylinder 3141 and the second hydraulic cylinder 3142. The cylinder body of the first hydraulic cylinder 3141 is fixed to the first support arm 3112, and its rod body is fixed to the first bearing seat 3114. The cylinder body of the second hydraulic cylinder 3142 is fixed to the second support arm 3113, and its rod body is fixed to the second bearing seat. The pressure accumulator 3143 stores energy and gradually increases in length as the rods of the first hydraulic cylinder 3141 and the second hydraulic cylinder 3142 contract. This ensures that the first and second hydraulic cylinders 3141 and 3142 can simultaneously control the first hollow roller 312 from both sides after the sweet sorghum enters between the first hollow roller 312 and the second hollow roller 313. This ensures that the first hollow roller 312 is as close as possible to the second hollow roller 313 and provides stable pressing of the sweet sorghum. The central axes of the first and second hydraulic cylinders 3141 and 3142 are positioned to pass through the central axes of the first and second hollow rollers 312 and 313, ensuring that the diameter of the first hollow roller 312 remains coplanar with the diameter of the second hollow roller 313, whether in a moving or stationary state, thereby guaranteeing effective pressing of the sweet sorghum.

[0062] Preferably, the plane containing the central axis of the first hollow roller 312 and the central axis of the second hollow roller 313 is a selected plane. The angle between the selected plane and the predetermined direction is an acute angle, and the acute angle is located on the feed side of the pressing mechanism. This helps guide the flow direction of sweet sorghum when it enters the first hollow roller 312 and the second hollow roller 313, so that the sweet sorghum can enter more smoothly, thereby improving the efficiency and uniformity of feeding.

[0063] Figure 5 A front view of the primary pressing mechanism 31 provided in this embodiment is shown. Figure 5 and combined Figures 1-4As shown, both the first hollow pressure roller 312 and the second hollow pressure roller 313 include a roller body 3121 and a plurality of convex ribs 3122 arranged circumferentially on the roller body 3121 and spaced apart axially. The convex ribs 3122 of the first hollow pressure roller 312 and the convex ribs 3122 of the second hollow pressure roller 313 are staggered axially in either one. When the first hollow pressure roller 312 and the second hollow pressure roller 313 rotate, the convex ribs 3122 effectively press the sweet sorghum, allowing juice to flow out from the gaps between adjacent convex ribs 3122. The staggered arrangement of the convex ribs 3122 helps guide the flow of sweet sorghum between the first hollow pressure roller 312 and the second hollow pressure roller 313, reducing the accumulation and adhesion of sweet sorghum between them, thus enabling more efficient conveying and processing of sweet sorghum.

[0064] Furthermore, both the first hollow pressure roller 312 and the second hollow pressure roller 313 include wavy grooves 3123 disposed on the pressure roller body 3121 and cutting off each of the protrusions 3122. The wavy grooves 3123 can drive the sweet sorghum between the first hollow pressure roller 312 and the second hollow pressure roller 313 from the feeding side to the discharging side to avoid the accumulation of sweet sorghum. The wavy grooves can drive all the sweet sorghum between the first hollow pressure roller 312 and the second hollow pressure roller 313 in stages (that is, when the first hollow pressure roller 312 and the second hollow pressure roller 313 rotate at a certain angle, some of the sweet sorghum in the wavy grooves 3123 are driven), thereby reducing the load on the first hollow pressure roller 312 and the second hollow pressure roller 313.

[0065] Furthermore, the first hollow pressure roller 312 includes a juice inlet 3124 disposed on its protrusion 3122 and communicating with the interior of the pressure roller body 3121, and a juice outlet 3125 disposed on the end surface of the pressure roller body 3121. The cooperation of the juice inlet 3124 and the juice outlet 3125 allows a portion of the juice to first enter the first hollow pressure roller 312 and then flow out of the first hollow pressure roller 312, thus achieving juice flow control. The second hollow pressure roller 313 includes a juice inlet disposed on its protrusion and communicating with the interior of the pressure roller body, and a juice outlet 313 disposed on the end surface of the pressure roller body. The cooperation of the juice inlet and the juice outlet allows a portion of the juice to first enter the second hollow pressure roller 313 and then flow out of the second hollow pressure roller 313, thus achieving juice flow control.

[0066] It should be noted that in this embodiment, the first hollow pressure roller 312 and the second hollow pressure roller 313 have nearly the same mechanical structure. The main difference is that their sizes are different. To save space, this embodiment only shows the structural schematic diagram of the first hollow pressure roller 312 and describes the specific structure of the primary pressing mechanism in detail.

[0067] Figure 6A cross-sectional view of the primary pressing mechanism 31 provided in this embodiment is shown, as follows: Figure 6 and combined Figures 1-5 As shown, the primary pressing mechanism 31 and the secondary pressing mechanism 32 also include a first comb plate 315 mounted on the frame for removing the adhesive material on the first hollow pressing roller 312, and a second comb plate 317 mounted on the frame for removing the adhesive material on the second hollow pressing roller 313, so as to remove the adhesive material (sweet sorghum after pressing) on ​​the first hollow pressing roller 312 and the second hollow pressing roller 313, and prevent the adhesive material from accumulating and affecting the normal operation of the first hollow pressing roller 312 and the second hollow pressing roller 313.

[0068] Furthermore, the primary pressing mechanism 31 and the secondary pressing mechanism 32 also include a first pallet 316, see [link / reference]. Figure 6 The first tray 316 is mounted on the frame and is used to guide the sweet sorghum smoothly into the space between the first hollow pressure roller 312 and the second hollow pressure roller 313, so as to achieve efficient introduction of sweet sorghum.

[0069] Furthermore, the primary pressing mechanism 31 and the secondary pressing mechanism 32 also include an input roller 318 and an output roller 319. The input roller 318 is rotatably mounted on the frame and, when rotating, inputs the sweet sorghum between the first hollow roller 312 and the second hollow roller 313, providing additional power when the sweet sorghum is introduced between the first hollow roller 312 and the second hollow roller 313. The output roller 319 is rotatably mounted on the frame and, when rotating, assists the first hollow roller 312 and the second hollow roller 313 in outputting the sweet sorghum, providing additional power when the sweet sorghum is discharged from between the first hollow roller 312 and the second hollow roller 313. The feeding roller 318 and the output roller 319 can prevent the sweet sorghum from getting clogged due to insufficient power when it is being fed in and out, which helps to maintain the efficient operation of the primary pressing mechanism 31 and the secondary pressing mechanism 32 and reduces the probability of the primary pressing mechanism 31 and the secondary pressing mechanism 32 going down.

[0070] Continue to refer to Figure 1 and Figure 2 As shown, the integrated sweet sorghum harvesting, pressing, and storage machine also includes a gathering and conveying device 6 installed on the motor vehicle 1. The gathering and conveying device 6 is located between the juicing device 3 and the crushing and throwing device 7, and is used to convey the pressed sweet sorghum into the crushing and throwing device 7, so that the crushing and throwing device 7 can crush and throw the sweet sorghum.

[0071] Figure 7 A structural diagram of the diffusion conveying device 33 provided in this embodiment is shown. Figure 8 A top view of the gathering and conveying device 6 provided in this embodiment is shown. Figure 9 A schematic diagram of the structure of the fabric roller 3331 provided in this embodiment is shown. Figures 7-9 and combined Figures 1-6 As shown, both the diffusion conveying device 33 and the gathering conveying device 6 include a second frame 331, a first conveyor 332, and a fabric roller assembly 333. The first conveyor 332 is located inside the second frame 331. The fabric roller assembly 333 includes at least two fabric rollers 3331 arranged above the first conveyor 332 and spaced apart along the length of the first conveyor 332. Each fabric roller 3331 includes a roller body 33311 rotatably disposed within the second frame 331, and a first helical blade 33312 and a second helical blade 33313 wound around the outer circumferential surface of the roller body 33311. The first helical blade 33312 and the second helical blade 33313 are mirror-symmetric about a selected section of the roller body 33311. The selected section refers to the section perpendicular to the central axis of the roller body 33311 and passing through the midpoint of the width direction of the roller body 33311. In this system, the spreading roller assembly 333 and the first conveyor 332 clamp each other to transport sweet sorghum along the length of the first conveyor 332. Each spreading roller 3331 within the spreading roller assembly 333 uses its respective first helical blade 33312 and second helical blade 33313 to cause the transported sweet sorghum to spread or gather in the width direction of the first conveyor 332. On one hand, the first helical blade 33312 and second helical blade 33313 can compress the sweet sorghum relative to the smooth spreading roller 3331, ensuring that the sweet sorghum can be stably transported along the length direction of the first conveyor 332 under the combined clamping of the first conveyor 332 and the spreading roller assembly 333. On the other hand, the opposite helical directions of the first helical blade 33312 and second helical blade 33313 can cause the sweet sorghum to spread or gather in the width direction of the first conveyor 332 while being transported along its length. The coordinated action of the first conveyor 332 and the cloth roller assembly 333 achieves precise clamping and conveying of sweet sorghum. The diffusion conveyor 33 and the gathering conveyor 6 effectively solve the problem of traditional conveying devices being unable to adjust in the width direction, allowing for better matching with the primary pressing mechanism 31, the secondary pressing mechanism 32, and the crushing and throwing device 7. During the pressing process, the diffusion conveyor 33 can adapt the sweet sorghum output from the primary pressing mechanism 31 to the receiving range of the secondary pressing mechanism 32, thereby improving the working efficiency of the secondary pressing mechanism 32. During the throwing process, the gathering conveyor 6 can adapt the sweet sorghum after pressing by the secondary pressing mechanism 32 to the receiving range of the crushing and throwing device 7, reducing the waste of sweet sorghum and improving the overall efficiency and accuracy of the operation.

[0072] Specifically, the diffusion conveying device 33 and the gathering conveying device 6 have nearly similar mechanical structures, the main difference being the orientation of their input and output ends on the integrated sweet sorghum harvesting, crushing, and storage machine. For example... Figure 7 and combined Figures 1-8 As shown, looking along the direction from the input end to the output end of the first conveyor 332, the structure of the first spiral blade 33312 and the second spiral blade 33313 at their intersection is an inverted herringbone shape, and the sweet sorghum is diffused towards the width direction of the gathering conveyor 6 by the rolling of the roller 33311. Figure 9 A top view of the diffusion conveying device 33 provided in this embodiment is shown, as follows: Figure 9 and combined Figures 1-8 As shown, the structure of the first spiral blade 33312 and the second spiral blade 33313 at the intersection of the first conveyor 332 from the input end to the output end is herringbone shaped, and the sweet sorghum is gathered in the width direction of the diffusion conveying device 33 by the rolling of the roller 33311.

[0073] The first helical blade 33312 and the second helical blade 33313 are mirror-symmetric about a selected section of the roller 33311. The selected section is the section perpendicular to the central axis of the roller 33311 and passing through the midpoint of the width direction of the roller 33311, so that the sweet sorghum conveyed along the length direction of the first conveyor 332 is evenly diffused or gathered.

[0074] Furthermore, the second frame 331 includes a first guard plate 3311 and a second guard plate 3312 arranged symmetrically. A chain conveyor is installed between the first guard plate 3311 and the second guard plate 3312. A material roller assembly 333 is also installed between the first guard plate 3311 and the second guard plate 3312. The symmetrical arrangement of the first guard plate 3311 and the second guard plate 3312 can effectively prevent materials from shifting or scattering during the conveying process.

[0075] Furthermore, the thickness of the first guard plate 3311 and the thickness of the second guard plate 3312 gradually increase along the length of the first conveyor 332 to cooperate with the fabric roller group 333, so that the sweet sorghum transported along the length of the first conveyor 332 can be effectively gathered.

[0076] Continue to refer to Figure 7 and combined Figures 1-6As shown, the diffusion conveying device 33 and the gathering conveying device 6 also include a transmission mechanism 334 located in the second frame 331 and connected to multiple fabric rollers 3331. The transmission mechanism 334 is used to transmit the power generated by the power unit of the motor vehicle 1 to each fabric roller 3331, and to make the linear speed of each fabric roller 3331 decrease or increase along the conveying direction of the first conveyor 332, so that the speed of the sweet sorghum conveyed along the length direction of the first conveyor 332 gradually decreases or increases, in order to cooperate with the diffusion or gathering effect of the first spiral blade 33312 and the second spiral blade 33313, so as to be able to adapt more smoothly to the processing requirements of pressing or throwing processes in subsequent processes.

[0077] Specifically, the number of fabric rollers 3331 is N, where N is a positive integer greater than or equal to 2. The transmission mechanism 334 includes an i-th belt drive assembly located between the i-th fabric roller 3331 and the (i+1)-th fabric roller 3331. The i-th fabric roller 3331 is adjacent to the (i+1)-th fabric roller 3331 and is closer to the input side of the first conveyor 332 than the (i+1)-th fabric roller 3331. The i-th belt drive assembly includes an i-th drive pulley 3341 located on the i-th fabric roller 3331 and a drive pulley 3341 located on the (i+1)-th fabric roller 3331. The i-th driven pulley 3342 on 3331, and the i-th synchronous belt 3343 fitted on the i-th driving pulley 3341 and the i-th driven pulley 3342, wherein the number of teeth of the i-th driving pulley 3341 is less than or greater than the number of teeth of the i-th driven pulley 3342, where i∈[1,N-1]. Through the cooperation of the driving pulley 3341, the driven pulley 3342 and the synchronous belt 3343, the linear speed of each fabric roller 3331 can be arranged to gradually decrease or gradually increase along the length direction of the first conveyor 332.

[0078] For example, when there are two fabric rollers 3331, the transmission mechanism 334 includes a first belt drive assembly disposed between the first fabric roller 3331 and the first+1 fabric roller 3331, and the first fabric roller 3331 is adjacent to the second fabric roller 3331 and is closer to the input side of the first conveyor 332 than the second fabric roller 3331. The first belt drive assembly includes a first driving pulley 3341 disposed on the first fabric roller 3331, a first driven pulley 3342 disposed on the second fabric roller 3331, and a first synchronous belt 3343 sleeved on the first driving pulley 3341 and the first driven pulley 3342, wherein the number of teeth of the first driving pulley 3341 is less than or greater than the number of teeth of the first driven pulley 3342.

[0079] Furthermore, the second frame 331 includes a first groove 3313 that rotatably accommodates the first end of the fabric roller 3331, and a second groove 3314 that rotatably accommodates the second end of the fabric roller 3331. The first groove 3313 and the second groove 3314 are strip-shaped holes. The first groove 3313 and the second groove 3314 can provide movement space for the fabric roller 3331, so that the distance between the fabric roller 3331 and the first conveyor 332 can vary to suit the thickness of the sweet sorghum between them, thereby making the diffusion conveying device 33 or the gathering conveying device 6 better adaptable to the conveying of sweet sorghum.

[0080] The first conveyor 332 is preferably a chain plate conveyor, which includes a frame, chain plates 3321 disposed within the frame for supporting the first conveyor 332, and multiple support rollers for supporting the chain plates 3321. The multiple support rollers are arranged at intervals along the length direction of the first conveyor 332. The chain plates 3321 can prevent sweet sorghum from falling off during the conveying process along the length direction of the first conveyor 332, and the support rollers can provide effective support for the chain plates 3321 to prevent the chain plates 3321 from collapsing during the conveying of a large amount of sweet sorghum by the first conveyor 332.

[0081] Figure 10 A schematic diagram of the structure of the crushing and throwing device 7 provided in this embodiment is shown, as follows: Figure 10 and combined Figures 1-9 As shown, the crushing and throwing device 7 includes a conveying pipe 71, a crusher 72, and an exhaust fan 73. The conveying pipe 71 is mounted on the motor vehicle 1 and is used to receive the crushed sweet sorghum. The crusher 72 is located in the conveying pipe 71 and crushes the sweet sorghum passing through it. The exhaust fan 73 is located on the conveying pipe 71 and is able to discharge the crushed sweet sorghum outside the conveying pipe 71, thereby achieving the crushing of sweet sorghum and the discharge of the crushed sweet sorghum.

[0082] like Figure 2 and combined Figures 1-10 As shown, the integrated sweet sorghum harvesting, pressing, and storage machine also includes a feeding device 8 mounted on the motor vehicle 1 and located between the harvesting device 2 and the pressing device 3. The feeding device 8 includes a second conveyor and a feeding roller assembly located above the second conveyor. The feeding roller assembly and the second conveyor clamp the sweet sorghum along the length of the second conveyor. Exemplarily, the feeding rollers of the feeding roller assembly can be selected as cloth rollers 3331 without spiral blades, and the second conveyor can be selected as a chain conveyor.
